WILLIAM H. DANIELS, OF ST. LOUIS, MISSOURI, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO THE ST. LOUIS CAR-AXLE LUBRICATOR COMPANY, OF SAME PLACE.

CAR-AXLE LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 498,772, dated June- 6, 1893.

Application filed October 4:, 1892.

To all whom it may concern:

Be it known that I, WILLIAM H. DANIELS, a citizen of the United States, residing at the city of St. Louis and State of Missouri, have invented a certain new and useful Improvement in Car-Axle Lubricators, of which the following is such a full, clear, and exact description as will enable any one skilled in-the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates mainly to that class of car axle lubricators in which a roller partly r 5 immersed in oil is operated by contact with the journal, to carry oil to the journal when the same revolves.

The object of the invention is to provide a lubricating appliance of the class aforesaid,

which may be readily removed and replaced, which is simple in construction, and which applies the lubricant in such a manner that its tendency to leak from the box will be very slight, and the usual drip-collar or equivalent 2 5 devices may be dispensed with. For this purpose I adapt the lubricating roller and parts connected thereto to be introduced into the box and to be removed therefrom as a whole, that is, without any portion thereof being 0 taken apart, and I so place the same in the box that the oil is applied near the outer end of the journal whereby, I find in practice, all portions of the journal are sufficiently lubricated, but there is little or no excess of oil on the journal where the same joins the axle, so that there will be only slight tendency of the oil to ooze out from the box where the axle enters the same.

The invention will be best understood by referring to the accompanying drawings, in which like marks of reference indicate like parts throughout the several views.

Figure 1 is a vertical sectional view on the plane of the line 11 of Fig.2, showing a box provided with my improvement. vFig. 2 is a transverse vertical sectional view on the plane of the line 22 of Fig. 1. Fig. 3 isa sectional plan view on the plane of line 3-3 of Fig. 2,

with the journal removed. Fig. 1 is a plan View of a detail.

10 is the oar-axle, 11 the journal thereof, and 12 the ordinary box that surrounds the journal and supports the body of thecar.

13 is the usual brass or anti-friction metal held in the upper part of the box, and which rests upon the journal and takes up the wear.

14 is a plate that surrounds the axle near the journal, and which is carried by the box to form a dust guard to prevent the dust from entering the box and commingling with the lubricant. The box has the usual opening normally closed by a lid 15, which is hinged to the box at 16.

The foregoing parts may be of the ordinary construction and form no part of my invention.

The lubricating roller 17, the lower portion of which runs in oil, is mounted on a journalpin 18 supported preferably by spring-arms 19 extending from a short shaft 21, which shaft is mounted beneath and to one sideof the journal 11. The roller 17 is held in contact with the under surface of the journal in any suitable manner, to wit: the arms 19 may be rigidly united to the shaft 21, and may be made of spring metal, so that when the device is looked in its place as hereinafter explained, the elasticity of the arms will hold the roller against the journal. If the arms are not themselves elastic, a spring may be employed to holdthe roller 17 in contact with thejournal as aforesaid. In the device shown in the drawings, for example, 20 is a flat spring, one end of which is curved about the shaft 21 and secured thereto by a bolt 22 or other suitable means, while the other or free end of the said spring presses against a cross-bar 23 which connects the spring-arms 19 together, the said spring-arms in this case being, of course, freelymounted on the shaft 21 (Fig. 3).

The bearings wherein is j ournaled the shaft 21, are preferably cast integral with the bottom of the box 12, and consist of two lugs 24 and 25. The lug 24 (Figs. 1 and 4) which I prefer to place about midway between the front end (or end closed by lid) of the box and the rear end of the box (or end where the axle enters same) has a bored out circular depression in its front face (or face turned toward the front end of the box 12). Into this depression loosely fits the rear end of the shaft 21. The bottom of the box 12 adjacent to said depression is raised somewhat, forming a sort of guide 26 converging toward said depression, to facilitate introducing the end of the shaft 21 into said depression, as hereinafter explained. The lug 25 which, by preference, is placed directly beneath the front end of the journal 11, is bifurcated at its top, forming an open bearing for the front end of shaft 21. The shaft 21 projects somewhat beyond this hearing, and carries at its projecting end a crank-like arm 27 rigidly united to said shaft, and which may be cast integral therewith.

The lubricating device is adapted to be locked in place by means of said arm 27 restin g against an an gle-iron catch 28 attached to the box 12 near the lid 15, and preferably cast integral with the box 12, the spring-arms 19 being so adjusted on shaft 21 that when the arm 27 is locked in its normal position (Fig. 2) by the catch 28, as aforesaid, the springarms 19 will be slightly depressed by the roller 17 coming againstthe journal 11, whereby said roller is held in contact with said journal with the requisite pressure.

In applying my device to a car the shaft 21, roller 17 and arm 27 are first put together, and are introduced as a whole into the box, the lid 16 beingopened for that purpose. The end of the shaft 21 is projected into the space back of the lug 25, and is directed by guide 26 into its bearings in the depression in the face of lug 24:- The other end of shaft 21 is then lifted over lug 25 and permitted to drop into its bifurcated bearing, arm 27 being locked in its normal position by the angle-iron 28 (Fig. 3). The roller 17 is now held in contact with the journal 11, the angle at which spring-arms 19 and the arm 27 are adjusted on shaft 21 being such that when arm 27 is locked in position the said springarms will be somewhat depressed by the roller 17 comingin contact with the journal 11, as

aforesaid. When the lubricating device is' to be. removed, the arm 27 is pressed against thetwisting action of the spring-arms 19, and is moved slightly away from the angle-plate 28'so as to be out of engagement therewith (see dotted lines Fig. 3). The front end of shaft 21 is then raised out of the bearing formed by the bifurcated lug 25, the boredout depression in lug 24 wherein rests the other end of shaft 21, being sufliciently large to permit the shaft 21 to be thus manipulated. The entire lubricating device may now be withdrawn from the box as a whole, as readily as it was introduced.

The shaft 21 should be made very short, because if too long, it will be unwieldy so that it and the locking arm 27 cannot be made in is achieved partly by making the shaft 21 very short so that the device may be introduced as a whole, and may be easily manipulated in the small space afforded for that purpose. Again, the guide 26 isa very important feature, as it directs the end of the shaft 21 to its bearing in lug 24, whereasheretofore it was a very tedious task in lubricators of this class, to introduce the shaft into its bearings, the same being necessarily hidden from view and out of reach.

Another advantage of my lubricator consists in applying the oil to the outer or front part of the axle, so that the excess of oil drips off before reaching the rear or inner end of the journal. In this manner the ordinary drip-cup is dispensed with, and the oozing out of the oil between the axle and the box is practically prevented. The simplicity and consequent cheapness of this lubricating appliance will be apparent.

Another advantage is the fact that when introduced, the device need not be keyed up or adjusted so as to apply the roller 17 to the journal, the spring-arms 19 and locking arms 27 being so adjusted in advance that when the device is in place, the roller will be properly held in contact with the journal in the manner hereinbefore fully set forth.

Having fully described my invention, what I desire to claim and secure by Letters Patent of the United States is- 1. An oil-conveyer carried by a removable shaft, a bearing wherein the rear or inner end of said shaft is adapted to rest, and a guide leading toward said bearing, whereby the end of the shaft will be directed into said bearing when the device is being placed in position.

2. An oil-conveyer carried by a removable shaft, a bearing wherein the rearor inner end of said shaft is adapted to rest, a guide leading toward said bearing, whereby the end of the shaft will be directed into said bearing when the device is being placed in position, a locking arm suitably united to said shaft, and a catch for engaging said locking arm.-

3. The combination of an oil-conveying roller, spring-arms for holding the same in contact with the journal, a short shaft carrying said spring-arms, suitable bearings for removably holding said shaft, a locking arm IIO rigidly united to said shaft and suitably ad- In testimony whereof I have hereunto set justed thereon relative to said spring-arms, my hand, this 27th day of September, 1892; in 10. arlild a catch for engaging said locking arm, the presence of thetwo subscribing'witnesses. W ereby the roller will be brought and held 1 5 suitably in contact with the journal by si1n WILLIAM DANIELb' ply introducing the device as a whole into its Witnesses: position in the box, without winding or key- A.
